Don't do any moving or cleaning until the appraiser see's the area.
You will have extensive cleaning and home repairs. I would first move up all the electrical cords and surge protectors that are on the wet flooring and put them up high or on platforms. You want to eliminate any electrical shocks or hazzards.
After he/she comes out, then re post and we will tell you some things to do.
Anything that you move or alter, take a picture of it before you do so.
